Thus finding this information will be difficult. Traveling by car should have some features which can be detected statistically. High speed, small slowdown when going uphill, rarely passing over footways etc.

If you have only a docent track? right. But what if you have 100 tracks? Or 1000? It's going to need a health dose of advanced statistics so.
